USB-Powered High Voltage Supply
Aylo6061 has created a high voltage power supply of 300 volts from a USB power supply, which will be used for electrophoresis or electrowetting. The circuit is designed with double insulation and complete isolation between high and low voltage sides, making it safe to use. The control circuitry is based on an RP2040 chip with USB isolation for data lines. The project code is available on GitHub.
